‘The Bills’ offense — at least through three quarters — was woefully inept, continuing a season-long trend; Johnson, despite the fact that he rallied the team back into the game in the fourth quarter, suffered through a very tough day, and it ended with a separated shoulder that will sideline him 2-4 weeks; The normally solid defense was burned for a couple of long touchdowns and 24 points overall; Guard Ruben Brown engaged line coach Carl Mauch in a visible shouting match on the sidelines; Chargers head coach Mike Riley made a second-guesser’s dream come true by playing backup quarterback Moses Moreno for two series in the second quarter. In four plays, Moreno lost two fumbles deep in Chargers territory that set up a pair of Buffalo touchdowns. Imagine where the Bills would be today if San Diego starter Jim Harbaugh hadn’t been relegated to the sidelines during that stretch.’
